> Currently, if admin setup labels on queues

> This is not a good user experience, we should stop fail RM so that admin can 
> configure queue/labels in following steps:
> - Configure queue (with label)
> - Start RM
> - Add labels to RM
> - Submit applications
> Now admin has to:
> - Configure queue (without label)
> - Start RM
> - Add labels to RM
> - Refresh queue's config (with label)
> - Submit applications
